Firmware Upgrade
This section provides information on actions that should be taken before starting a firmware upgrade on the
Ultrastar Data60.
The storage administrator should determine if the applications on the enclosure should be quiesced before
the online upgrade is completed. Before upgrading enclosure firmware, review the following section to determine
whether or not the enclosure should be taken offline before upgrading. As an alternative to the automatic
firmware upgrade activation process, the storage administrator may opt to use a more controlled process by
using the non-automatic firmware activation process detailed in
on page
150 and
Windows Upgrade to New Firmware
on page 155.
Attention: It is strongly recommended that the user use the non-automatic firmware activation process
for either Linux or Windows.
SAS Configuration: If the enclosure contains SAS drives and redundant IOMs, the enclosure firmware may
be upgraded while online. This is due to the SAS configuration and host being able to manage the firmware
upgrade using host multi-pathing software. The storage administrator should ensure that there are always
two paths to each drive before starting an upgrade on either IOM. This will ensure that at least one path to
each drive is available during the reset of the IOM that is being upgraded.
After the firmware has been downloaded to one IOM, the IOM will reset and boot to the new firmware. Before
proceeding with the upgrade on the second IOM, ensure that each drive has two available paths to guarantee
that there is a redundant path is available to service I/O.
SATA Configuration: If the enclosure contains SATA drives, the enclosure firmware should not be upgraded
while online. This is due to the configuration having no redundancy due to only having a single IOM. When
the IOM is rebooted, the single path to the drives to service I/O will be taken down and restored to service
when finished booting.
Users should install all of the required downloads before beginning the firmware upgrade process.
Devices (<dev>)
In order to initiate a firmware upgrade on the enclosure, a target must be identified. Linux targets are referred
to as sg (SCSI Generic) devices and appear as /dev/sgX in the Linux Firmware Upgrade procedure. Windows
targets are referred to as SCSI devices and appear as SCSI<dev> in the Windows Firmware Upgrade.
Required Downloads:
• SG3 Utils: download version 1.42 from the SG3 Utils website at:
http://sg.danny.cz/sg/sg3_utils.html
Note: Firmware upgrades do not affect any zoning configurations that have been enabled on the
enclosure.
